01 - Rinse the rice under cold water until water runs clear. Combine rice, 2 cups water, and 1/2 tsp salt in a saucepan. Bring to a rolling boil over high heat, reduce heat to low, cover tightly, and simmer for 15 minutes. Remove from heat and let stand covered for 5 minutes before fluffing with a fork.
02 - Pat chicken pieces dry with paper towels. Season evenly with 1 tablespoon Cajun seasoning, smoked paprika, black pepper, and 1/2 tsp salt. Toss to coat thoroughly.
03 - Heat olive oil in a large skillet over medium-high heat until shimmering. Add seasoned chicken in a single layer. Cook undisturbed for 3-4 minutes until golden brown, then flip and cook another 3-4 minutes until cooked through and internal temperature reaches 165°F. Transfer chicken to a plate and set aside.
04 - In the same skillet, add diced onion and bell peppers. Sauté for 3-4 minutes until vegetables begin to soften and onions turn translucent. Add minced garlic and cook for 1 minute until fragrant, being careful not to burn.
05 - Reduce heat to medium. Pour in chicken broth, using a wooden spoon to scrape up browned bits from the bottom of the pan. Stir in heavy cream and cream cheese. Continue stirring until cream cheese melts completely and sauce is smooth and bubbling.
06 - Return browned chicken to the skillet along with any accumulated juices. Add remaining 1/2 tablespoon Cajun seasoning and grated Parmesan. Stir gently until sauce thickens slightly and coats the chicken evenly. Simmer for 3-4 minutes until heated through.
07 - Divide fluffy rice among four serving bowls. Top generously with creamy Cajun chicken and vegetable mixture. Garnish with sliced green onions and fresh parsley. Serve immediately while hot.
